Description

Technical Field

[0001] This utility model relates to the technical field of packaging equipment, and in particular to an adjustable limiting device for small card packaging. Background Technology

[0002] In the production of mini-SIM cards in the telecommunications workshop, the cards need to be packaged to seal them in plastic film. The packaging requires the mini-card to be centered within the plastic film to prevent misalignment, scratches, or other issues. Currently, mini-SIM packaging equipment uses pressure blocks to restrict the position of the mini-cards. These blocks are fixed to the transmission track, allowing only the mini-card to pass through. This method of limiting position can easily cause the mini-card to jam on the transmission track and scratch the packaging film, leading to sluggish operation of the packaging equipment and packaging quality problems. Furthermore, because the pressure blocks are fixed to the packaging equipment, their height is fixed and cannot be adjusted according to the thickness of the mini-card and the plastic film. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an adjustable limiting device for small card packaging that has a good limiting effect, can adapt to products of different thicknesses and is not easily damaged.

[0004] The technical solution adopted by this utility model is as follows: This utility model includes a support base and two limiting mechanisms. The support base has a connecting hole, and the two limiting mechanisms are connected to the connecting hole. Each limiting mechanism includes a screw, the lower end of which passes through the connecting hole from top to bottom and is rotatably connected to a rotating seat. The upper end of the screw is located above the connecting hole and is connected to an adjusting component. A spring is sleeved on the screw and is located between the support base and the rotating seat. During packaging, the two rotating seats are located on the packaging film and respectively limit the two sides of the small card.

[0005] Furthermore, the rotating seat is rotatably connected to the screw via a bearing.

[0006] Furthermore, the upper end of the rotating seat has a fixedly connected end cap, and the end cap has a through hole for the screw to pass through.

[0007] Furthermore, the bottom height of the rotating seat is greater than the thickness of the packaging film and less than the thickness of the card.

[0008] Furthermore, the support base includes a top connecting plate and two bottom support blocks, the two bottom support blocks being located on both sides of the packaging film, and the two ends of the top connecting plate being connected to the two bottom support blocks respectively.

[0009] Furthermore, the connecting hole is a U-shaped hole.

[0010] Furthermore, the adjusting component is a wing nut.

[0011] The beneficial effects of this utility model are:

[0012] In contrast to the shortcomings of existing technologies, this invention places a small card on the packaging film and keeps it centered. Two rotatable seats limit the movement of the small card on both sides, ensuring its centered position. Adjustable components allow for adjustment of the bottom height of the rotating seats to accommodate the thickness of the small card and the packaging film. Furthermore, a spring above the rotating seats ensures that the height of the seats can adapt to the changing conditions as the small card passes through, preventing jamming. This prevents damage such as jamming or scratches during transport, achieving precise positioning. Therefore, this invention offers advantages such as good positioning performance, adaptability to products of different thicknesses, and minimal risk of product damage. Attached Figure Description

[0023] like Figures 1 to 3 As shown, in this embodiment, the present invention includes a support base 1 and two limiting mechanisms 2. The support base 1 has a connecting hole 3, and the two limiting mechanisms 2 are connected to the connecting hole 3. Each limiting mechanism 2 includes a screw 5, the lower end of which passes through the connecting hole 3 from top to bottom and is rotatably connected to a rotating seat 6. The upper end of the screw 5 is located above the connecting hole 3 and is connected to an adjusting member 7. A spring 12 is sleeved on the screw 5 and is located between the support base 1 and the rotating seat 6. During packaging, the two rotating seats 6 are located on the packaging film 8 and respectively limit the two sides of the small card 9.

[0024] During operation, first loosen the adjusting piece 7, adjust the position of the rotating seat 6 to press down the packaging film 8, and keep the small card 9 in the middle of the packaging film 8; then further tighten the adjusting piece 7 to ensure that the bottom height of the rotating seat 6 is greater than the thickness of the packaging film 8 and less than the thickness of the small card 9, thereby maintaining the height position of the small card; for example, when the thickness of the small card is 0.8mm and the thickness of the film is 0.25mm, the bottom height of the rotating seat 6 is adjusted to between 0.4mm and 0.6mm.

[0025] In contrast to the shortcomings of existing technologies, this invention places the small card 9 on the packaging film 8 and keeps it centered. Two rotatable rotating seats 6 limit the movement of the small card 9 on both sides to ensure its centered position. The bottom height of the rotating seats 6 can be adjusted by adjusting the adjusting component 7 to accommodate the thickness of the small card 9 and the packaging film 8. At the same time, a spring 12 is provided above the rotating seats 6. The elasticity of the spring 12 ensures that the height of the rotating seats 6 can be adaptively adjusted as the small card 9 passes through, preventing jamming. This ensures that the small card 9 will not jam, scratch, or be damaged during transmission, achieving precise positioning. As a result, this invention has the advantages of good positioning effect, adaptability to products of different thicknesses, and less risk of product damage.

[0026] In some embodiments, the bottom height of the rotating seat 6 is greater than the thickness of the packaging film 8 and less than the thickness of the small card 9. Specifically, the bottom height of the rotating seat 6 can be directly adjusted by the adjusting member 7, thereby keeping the packaging film 8 at the bottom of the rotating seat 6 and the small card 9 on the side of the rotating seat 6; the position of the small card 9 is restricted by the two rotating seats 6 to ensure that the small card 9 is located in the middle of the packaging film 8; wherein the horizontal gap between the rotating seat 6 and the small card 9 ranges from 1mm to 3mm.

[0027] In some embodiments, the rotating seat 6 is rotatably connected to the screw 5 via a bearing 13; the upper end of the rotating seat 6 has a fixedly connected end cap 10, and the end cap 10 has a through hole 11 for the screw 5 to pass through; specifically, the rotating seat 6 has a mounting hole, the bearing 13 is installed in the mounting hole and sleeved on the screw 5, so that the rotating seat 6 can be rotatably connected to the screw 5 via the bearing 13; when the small card 9 passes through, the rotating seat 6 can rotate to ensure that the small card is not excessively squeezed, thereby avoiding scratches and packaging damage.

[0028] In some embodiments, the support base 1 includes a top connecting plate 15 and two bottom support blocks 16, with the two bottom support blocks 16 located on opposite sides of the packaging film 8. The two ends of the top connecting plate 15 are respectively connected to the two bottom support blocks 16. Specifically, both ends of the top connecting plate 15 have openings, and the plate is fixedly connected to the bottom support blocks 16 through these openings to secure the entire device to the card packaging equipment.

[0029] In some embodiments, the connecting hole 3 is a U-shaped hole; the adjusting element 7 is a wing nut. Specifically, by setting the U-shaped hole, the screw 5 and the wing nut can lock the spring 12 and the rotating seat 6 into the U-shaped hole located on the support base 1, so that the entire device is connected as one unit, and the positions of the two rotating seats 6 can be adjusted.

[0030] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
